Suncom Aerobics Joystick

The Aerobics Joystick by Suncom promised an improved cardiovascular system from using this device that interfaced between most standard exercise bikes and an Atari 2600. While the fire button-equipped joystick worked with shoot-'em-ups, best results were obtained with driving games (particularly, Suncom said, Enduro). The faster you pedal, the faster you drive.

What could be more boring than pedaling a stationary bike--or worse exercise (thumb and forefinger excluded) than wiggling a joystick? Suncom combined the two activities to their mutual benefit. Price was $39.95.
